Revised January 1999 CD4047BC CD4047BC Low Power Monostable/Astable Multivibrator s Only one external R and C required General Description The CD4047B CD4047B is capable of operating in either the monostable or astable mode. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode, and the output frequency in the astable mode. Astable operation is enabled by a high level on the astable input or low level on the astable input. The output frequency (at 50% duty cycle) at Q and Q outputs is determined by the timing components. A frequency twice that of Q is available at the Oscillator Output; a 50% duty cycle is not guaranteed. MONOSTABLE MULTIVIBRATOR FEATURES s Positive- or negative-edge trigger s Output pulse width independent of trigger pulse duration s Retriggerable option for pulse width expansion s Long pulse widths possible using small RC components by means of external counter provision s Fast recovery time essentially independent of pulse width s Pulse-width accuracy approaching 100% maintained at Monostable operation is obtained when the device is triggered by LOW-to-HIGH transition at + trigger input or HIGH-to-LOW transition at - trigger input. The device can be retriggered by applying a simultaneous LOW-to-HIGH transition to both the + trigger and retrigger inputs. cycles s Free-running or gatable operating modes A high level on Reset input resets the outputs Q to LOW, Q to HIGH. duty s Good astable frequency stability ASTABLE MULTIVIBRATOR FEATURES s 50% duty cycle s Oscillator output available typical= ±2% + 0.03%/°C @ 100 kHz Features frequency= ±0.5% + 0.015%/°C @ 10 kHz s Wide supply voltage range: deviation (circuits trimmed to frequency VDD = 10V ±10%) 3.0V to 15V s High noise immunity: 0.45 VDD (typ.) s Low power TTL compatibility: or 1 driving 74LS Fan out of 2 driving 74L Applications · Frequency discriminators · Timing circuits SPECIAL FEATURES s Low power consumption: special CMOS oscillator configuration · Time-delay applications s Monostable (one-shot) or astable (free-running) operation · Frequency multiplication · Envelope detection · Frequency division s True and complemented buffered outputs Ordering Code: Order Number Package Number Package Description CD4047BCN CD4047BCN N14A 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001 MS-001, 0.300" Wide CD4047BCM CD4047BCM M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012 MS-012, 0.150" Narrow Body Devices also available in Tape and Reel.
